Bačka Tvrđava, Bač
The fortress in Bač is the most significant and best-preserved medieval fortification in the area of Vojvodina. The site where the fortress was built testifies to the long series of centuries of use of this naturally defensible terrain, which tied its fate to the Danube River, a natural border between peoples and civilizations. On the naturally elevated terrain, created by the meandering of the Mostonga River, there was a palisaded suburb with an east-west direction, which was entered via a bridge and through an entrance tower with a gate. In the northwestern part of the meander, on the island, there was a fortified castle that could be reached by passing through a separate barbican, surrounded by water on all sides. The plateau on which the fort was built is relatively small in size and covers an area of 8,700 m2. The base of the fortress, with an area of 5,600 m2, is in the shape of a trapezoid, adapted to the shape of the terrain. At the corners, there were five projecting defensive towers, interconnected by a rampart 2 m wide and 12 m high, with shooting lanes. The towers are of different shapes and sizes. The eastern part of the fortress was the best defended, since there is a defender-donjon tower and a residential palace, economic facilities along the western rampart and a series of grain pits. All buildings were built of brick with the use of stone for decorative elements.
